What Is Anxiety?

Anxiety is the body’s natural response to stress. It’s a feeling of fear, worry, or unease that can be triggered by a situation or occur without any obvious cause. While occasional anxiety is normal, persistent and excessive anxiety that impacts quality of life may indicate an anxiety disorder.

Common Signs of Anxiety

Anxiety affects people in different ways. Symptoms can appear physically, emotionally, and even behaviorally. Here’s what to watch for:

1. Physical Signs of Anxiety

Anxiety often causes noticeable changes in the body, including:

• Increased heart rate or palpitations
• Shortness of breath
• Muscle tension or aches
• Fatigue or low energy
• Sweating or clammy hands
• Headaches or dizziness
• Upset stomach, nausea, or diarrhea
• Shaking or trembling
• Insomnia or difficulty staying asleep

These physical symptoms may feel like something more serious, such as a heart problem, which is why many people visit the doctor before realizing it’s anxiety.
